Soybean storage precautions

Soybean is one of the most important food crops in China, and its protein content is very high. Many problems should be paid attention to when storing after harvest. Once the storage method is improper, it may lead to deterioration, mildew and seriously affect the quality of soybean. So what should you pay attention to when reaching storage? Let's get to know it.

1. Fully dry

Soybeans are rich in protein and moisture, and are extremely prone to denaturation at high temperature, so it is necessary to dry and reduce moisture in time after threshing. The moisture content of soybeans that need to be stored for a long time should not exceed 12.5%. The water content is too high, and it is easy to mildew during storage. It must be stored at a low temperature during storage. Especially the seeds after drying. In order to avoid protein deterioration caused by high temperature accumulation, it must be spread out and cooled and stored in storage. Try to choose dry weather with plenty of sunshine when entering the storage. do not store in rainy and wet weather.

2. The seeds should not be piled too high.

When soybean seeds are stored, the temperature is below 15 degrees. When the water content is less than 12%, the stacking height is not easy to exceed 1.5 meters, so in order to avoid deterioration caused by accumulated heat, it is appropriate to pack 8 standard gunny bags. If the temperature and humidity are higher than the above standard, the height of the stack should be lowered accordingly, and the spacing between the stack and the wall, and between the stack and the stack should be reasonably arranged.

3. Timely ventilation

The moisture of the newly stored grain is uneven, coupled with post-ripening, the respiration is exuberant, and there is more accumulation of moisture and heat in the soybean heap, at the same time, it is also the season of falling temperature, so it is easy to appear the phenomenon of dew. Therefore, in about 3-4 weeks of soybean storage, timely ventilation, moisture and heat dissipation, increase the storage resistance of soybean.

4. It is not suitable to store with pesticides and fertilizers.

Soybeans should be stored in a special warehouse, and chemical fertilizers or pesticides should not be stacked in the storeroom to prevent the volatilization of chemical fertilizers and pesticides from entering the embryo, resulting in the decline of soybean seed vigor and quality.

5. Low temperature sealing

In winter storage, soybean can be frozen and stored in a warm and closed way, which can not only isolate the influence of external temperature and humidity and the infection of diseases and insect pests, but also prevent oil immersion and red change, which is beneficial to maintain the quality of soybean.
